Point counting is tricky business. I believe it is the reason most folks (OpenSSL, Crypto++, NSS, etc) stick with well known curves.
I don't know how to plug in a custom curve with OpenSSL (I have never had a need to do it), but I do know how with Crypto++. If I wanted to do so, I would use Marcel Martin's Elliptic Curve Builder (ECB) to generate domain parameters to meet security levels.
